摘要： A refrigerant compressor group for a refrigeration system, comprising at least two piston compressors that operate in parallel between a common low-pressure connector and a common high-pressure connector, wherein, for the purpose of adjusting it to different requirements, it is provided, in a refrigerant compressor group, for a variable overall mass flow throughput in the refrigerant compressor group to be adjustable in that, in the case of at least one of the piston compressors, its mass flow throughput is adjustable by speed selection with the aid of a frequency converter for the electric motor, and in that, in the case of at least one of the piston compressors, its mass flow throughput is adjustable by cylinder selection, and in that an operating condition controller for the refrigerant compressor group is provided which, on the basis of a performance request signal of the refrigeration system that is transmitted to the operating condition controller, controls the overall mass flow throughput by open or closed-loop control by predetermining the cylinder selection and the speed selection.

摘要： A screw compressor comprises two screw rotors arranged in a screw rotor chamber, and mounted on the compressor housing to be rotatable about respective screw rotor axes, and mesh with one another. At least one control slide is arranged in a slide channel of the compressor housing, adjacently to both screw rotors by means of slide compression wall surfaces, is movable in a displacement direction parallel to the screw rotor axes, is rigidly connected to a piston rod that leads to a cylinder assembly for moving the at least one control slide, and is guided relative to the compressor housing by means of a guide insert that movably receives the piston rod in the displacement direction. The piston rod is guided transversely to the displacement direction in the guide insert in elastically resilient fashion by means of a guide element.

摘要： In order to adapt to different operating conditions a screw expander, comprising an expander housing with a screw rotor chamber arranged therein, two screw rotors arranged in the screw rotor chamber and mounted rotatably in the expander housing, which screw rotors intermesh with their screw contours in order to receive working medium supplied by means of a high-pressure chamber arranged in the expander housing and in order to discharge said medium in the region of a low-pressure chamber arranged in the expander housing, and a generator driven by the screw rotors, it is proposed that the screw expander has at least one control slide, which is arranged in a slide channel of the expander housing and is adjacent to both screw rotors with slide wall surfaces, which control slide is movable in a displacement direction parallel to the screw rotor axes and is thereby configured to influence the final volume and/or the initial volume, and that a slide drive is provided for moving the control slide into different slide positions.

摘要： A thermally insulating sleeve for a compressor discharge pipe is provided. The insulating sleeve includes a non-metallic first half-sleeve having a first curved body portion and a first extended portion. The first curved body portion is configured to fit at least partially around a portion of the compressor discharge pipe. A non-metallic second half-sleeve has a second curved body portion configured to attach to the first curved body portion such that the first and second curved body portions completely encircle the portion of the compressor discharge pipe. The second half-sleeve includes a second extended portion configured to attach to the first extended portion. Each of the first and second extended portions include respective first and second cavities which, together, encase a temperature sensor in contact with, or in spaced relation to, the compressor discharge pipe.

摘要： In order to optimise a compressor, including a compressor housing, a scroll compressor unit that is arranged in the compressor housing and has a first compressor body and a second compressor body that is movable in relation to the first compressor body, an axial guide that supports the movable compressor body to prevent movements in the direction parallel to the centre axis of the stationary compressor body and, in the event of movements, guides it in the direction transverse to the centre axis, parallel to a plane perpendicular to the centre axis, an eccentric drive for the scroll compressor unit, wherein the eccentric drive has an entrainer that is driven by the drive motor, that revolves on a path about the centre axis and that, for its part, cooperates rotatably with an entrainer receptacle in the second compressor body, and a coupling that prevents the second compressor body from rotating freely, it is proposed that the axial guide should have a carrier element, which serves as a base for supporting a compressor body base, which carries the scroll vane, of the second compressor body against an axial support face, that the axial support face should be arranged radially outward of the entrainer, and that the coupling that prevents free rotation should have at least two coupling element sets that, for their part, include at least two coupling elements, and that the coupling element sets should be arranged radially outward of the axial support face.

摘要： A method of manufacturing a two-piece counterweight for a scroll compressor is provided. The method includes molding an outer plate, and molding a base having a first opening configured to receive a scroll compressor drive shaft having a longitudinal axis, and configuring the base for assembly and attachment to the drive shaft. The method also includes attaching the outer plate to the base such that the outer plate is axially offset from the base. In a particular embodiment of this method, the base and outer plate are molded from powdered metal. In certain embodiments, the base and outer plate include one or more openings aligned to permit attachment by inserting a mechanical fastener through the aligned openings. In alternate embodiments, the base and outer plate are attached via brazing or welding.

摘要： In order to improve a refrigerant compressor comprising a drive motor and a compressor unit which compresses a refrigerant entering through a suction inlet and allows it to exit through a pressure outlet in such a way that it works as reliably as possible, it is proposed that the refrigerant compressor comprise a compressor monitoring system which is integrated into a compressor control system and which determines a compressor condition by means of a first condition value that corresponds to a first saturation temperature in the suction inlet and a second condition value that corresponds to a second saturation temperature in the pressure outlet, and which compares the compressor condition with permissible compressor conditions lying in a given deployment field of a deployment diagram and initiates a process of switching-off the refrigerant compressor if the compressor condition departs from the deployment field.
